Hey everyone, I was just wondering if anyone could clear a few issues I'm having with black holes and wormholes. First, for an object above a black hole, wouldn't its gravitational potential energy be infinite, since it is above an object with infinite gravity, then causing another object with an ifinite gravitational pull? For something going through a wormhole, would the same thing happen? Would a light beam be infinitely blue-shifted causing it to have infinite enrgy and infinite gravity, collapsing the wormhole? There must be something wrong with that since alot of popular science shows talk about wormholes and that would completetly rule out wormholes as a travel possiblilty. Thanks.
